4 GSI Infrastructure: ChemGuess and MetGuess BundlesGSI_Chem_Bundle renamed to ChemGuess_BundleIntroduce MetGuess_Bundle as a means to ingest meteorological guesses into GSI:presently working for clouds-related fieldsbeing extended to work with basic fields (u, v ,tv, etc)anavinfo file:Updates made to chem_guess tableAdd met_guess table to control contents for MetGuess_BundleFuture work includes:Instantiation of ChemGuess and MetGuess Bundles

5 GSI Infrastructure Interface to AD/TL modelsInterfaces to Aerosols & CloudsInterface to AD/TL modelsAdding aerosols and clouds to Guess Bundle allows for these to be passed to CRTM; parameter in anavinfo tables determines what’s to feed to CRTM and how.Add flexible interface to allow for user-specific controls to handle aerosols and clouds (see Tutorial)Revisit to support ESMFAvailable interfaces exist now for at least three global AD/TL models:GEOS-5 FV-dynamicsGEOS-5 FV-cubed-dynamicsNCEP Perturbation model

7 New Instruments: MOPITT COMOPITT - Measurements Of Pollution In The TroposphereChanges entail:- mild change to obsmodadd usual suspects whenhandling new observingtypes, e.g.:- readCO- setupCO- intCO- stpCO- Estimate and set B(co).Four profiles of MOPITT CO are randomly placed on the globeand assimilated using GSI. Preliminary results are consistent withshape of averaging kernel.Cycling experiments are on the way.(from Andrew Tangborn)

8 New Instruments: OMPS O3 (OSSE)OMPS – Ozone Mapping and Profiler SuiteHigh Fidelity Measurements:Total column (like TOMS)Vertical profiles (like SBUV)OSSE Setting:Generate truth: MLS-O3 & OMI/TCSimulate Radiances – Forward RTApply Instrument ModelsRetrieve ProfilesAssimilate Retrievals (GEOS-5 DAS)1 degree resolutionResults show:Data are ingested into GSI at all levelsQC control works (but rate of rejection can be adjusted)Analysis works effectivelyPenalties are in good rangeTime series show fast convergencesOMA and OMF are all very small and OMA are smaller than OMF(from Philippe Xu)

9 New Instruments: OMPS O3 (OSSE)OMPS – Ozone Mapping and Profiler Suitea) 5 hPab) 100 hPaAnalysis error (%) of retrieved ozone assimilation from TRUTHAt 5 hPa errors are small in most of region; orbit tracks of OMPS analysis are noticeable.At 100 hPa errors are large where retrievals are most difficult: Tropics as the ozone value are very small (<0.1ppmv).(from Philippe Xu)

10 New Instruments: OMPS O3 (OSSE)OMPS – Ozone Mapping and Profiler SuiteRetrieved vs MLS TRUTH (%)OMPS sampled vs MLS TRUTH (%)Monthly Zonal Mean analysis errorsThe results show that OMPS data agree well with MLS in the stratosphere and in most of the troposphere.In the tropical UT and LS there is large discrepancy (%) between MLS and OMPS, where the ozone mixing ratio are very small (<0.1 ppmv); needs more work.(from Philippe Xu)

22 Closing RemarksCompleting comparison of SC and WC-4dVar in prototype GEOS-5 4dVar system.Making progress in bringing GEOS-5 Cubed-Sphere TLM and ADM to maturity.Started working on hybrid ensemble components for GEOS-5 3d- and 4d-Var.Collaboration with NCEP is ongoing and fundamentalfor the success of these implementation.
